Title: Device for detecting vinyl chloride in waste plastic
Inventor: KINOSHITA MASAO
IPC: G01N31/12
Filed: 1992-06-19
Abstract: PURPOSE:To surely examine the presence/absence of polyvinyl chloride in waste plastics by collecting air containing pyrolysis gases generated from the waste plastics from a probe and detecting HCl in the air. CONSTITUTION:When a probe 6 descends and approaches waste plastics P and the annular body 10 protruded downward of a descending distance adjusting device 5 touches the plastics P, the body 10 retreats into the probe 6 by a fixed distance against the compression resiliency of a spring 2. At the same time, the lower end of an exothermic body 1 touches the upper surface of the plastics P. As a result, the plastics P at the contact point on the upper surface is locally decomposed by the heat of the body 1. The air containing generated pyrolysis gases is sent to an HCl detector 4 by an aspirator 3 and the detector 4 examines the presence/absence of HCl in the air. When the air contains HCl, it means that the plastics P contains polyvinyl chloride.

Title: Production of doubleply pipes
Inventor: YOSHIDA TOSHIO
IPC: F16L9/02
Filed: 1980-11-19
Abstract: PURPOSE: To deform an inside pipe plastically in an early period, increase an elastic return difference of both pipes and increase the degree of fitting of the doubleply pipes by inserting the inside pipe into an outside pipe, applying pipe expanding force to the inside pipe, and applying compressive force in the axial direction of the inside pipe.  
     CONSTITUTION: Jack plates 6', 6' are brought in abutment on the inside pipe 2 forced into an outside pipe 1, and are connected to jack rods 7, 7. On the other hand, water as pipe expanding liquid is supplied through a water feed path 8 provided to the plate 6' and is filled in the pipe 2. thence, compressive force is applied by the plates 6, 6' in the axial direction of the pipe 2, and circumferential pipe expanding force P lower in set amt. than axial compressive force T is applied successively. Then, the circumferential direction is yielded early by the axial compressive force and abuts on the pipe 1, thereby expanding the pipe integrally to a prescribed diameter. When the pressure is reduced after this, both inside and outside pipes reduce diameters elastically. At this time, the elastic return difference of the pipes 2, 1 is increased by the plastic deformation of the pipe 2, whereby a sufficient interference is obtained.

Title: Inverter unit
Inventor: SHIMIZU MOTOHISA
IPC: H02M7/48
Filed: 1991-06-06
Abstract: PURPOSE:To make it possible to deal even with a special overload, e.g. a half- wave rectified overload, by enhancing protective effect of circuitry against a high peak current or an overload current. CONSTITUTION:The inverter unit comprises a pair of current detecting resistors R5, R6 each having one end connected with a common line and arranged in each of two conducting paths of a bridge type inverter circuit 9, and correction circuits 15, 16 for forming output current waveform signals by superposing a pair of output current signals, detected through the current detecting resistors R5, R6, in reverse phase and correcting a sine wave reference signal based on the output current waveform signal to deliver the corrected signal to a pulse width modulation circuit. Consequently, peak value of AC output current can be limited within a predetermined range. Furthermore, since the state of the AC output current can be accurately detected by detecting the load current value for every DC component, overcurrent value can accurately be detected even for a special load such as a half-wave rectified load.
